PepsiCo has concluded a review launched earlier this summer by naming Goodby Silverstein & Partners as the newest member of its creative agency roster.

The food and beverage giant announced in June that it had called upon a lineup of Omnicom-only agencies to pitch for creative responsibilities on its flagship brand and others across its multibillion dollar beverage business. The news marks another development in a relationship that has lasted more than 60 years.

“We are pleased to add Goodby, Silverstein & Partners to our diverse roster of creative agencies across our beverage business in the U.S.,” said Greg Lyons, CMO of PepsiCo’s North American beverages division. “We look forward to working with Goodby and continuing our longstanding partnership with Omnicom through the addition of another one of its agencies.”
